Patent GB-1292147-A (GB)
Title: Improvements in or relating to suspension units for mounting road wheels on vehicles
IPC: B60G15/14
Filed: 1969-12-10
Abstract: 1292147 Spring suspensions; mounting steerable wheels TRW Inc 10 Dec 1969 [20 Aug 1969] 60348/69 Headings B7D and B7H [Also in Division F2] A suspension unit 10 for mounting a road wheel 11 on a vehicle comprises a housing 13 having a cylindrical cavity 14 divided into two pressure chambers 47, 49 by a reciprocating piston 15, a passageway (59), 75 connecting each of the pressure chambers with a liquid reservoir 54 containing a gas spring 55, and a valve (80- 83) located in one, 75, of the passageways to prevent flow of liquid along that passageway from the reservoir to the relevant pressure chamber, 49, the other passageway (59) allowing flow in both directions. The pressure chamber 47 communicates with the reservoir via a restricted passageway 58, and a passageway (59, Figs. 6 and 7, not shown) containing a one-way valve (71) which opens to allow relatively free flow from the reservoir to the pressure chamber 47, but restricts flow in the opposite direction. The pressure chamber 49 communicates with the reservoir via a passageway 75 which is valved (Fig. 3, not shown) to allow flow from the chamber to the reservoir, but prevent it in the opposite direction. When the passageway 75 is covered by the piston 15, grooves 51 and 52 allow restricted flow between chambers 47 and 49. On upward movement of the piston from the position shown, liquid flows from the chamber 47 through the passageways 58 and 59 to compress the gas in the reservoir until the piston closes off first the passageway 58 and then the passageway 59, further piston movement being hydraulically stopped by the liquid remaining in the chamber 47. On subsequent downward movement of the piston liquid flows from the chamber 49 through the passageway 75 to the gas-containing reservoir until the piston closes this passageway (as shown). The unit is self-levelling. The piston co-operates with two passageways 86, 87 leading respectively to and from a supply of liquid in a chamber (85, Figs. 3-5, not shown). The unit mounts a steerable wheel 11. A splined shaft 23 extends slidably but non-rotatably into a splined cavity 40 in the piston and is rotated by a worm gear 24 in response to a steering signal. The corresponding rotation of the piston/piston-rod 17 rotates the axle 18 to turn the attached wheel 11. A tie-rod 33 connects the splined shaft 23 to a similar shaft on another wheel, both wheels therefore turning together in response to the single worm gear 24.

Patent GB-2016855-A (GB)
Title: Imaging of a sectional layer of a three-dimensional object
IPC: A61B6/03
Filed: 1979-03-09
Abstract: In tomosynthesis, plural sources 1, 2, 3, 4, form shadowgraph images P1, P2, P3, P4 of an object with features A, B from different perspective directions. In synthesising a selected sectional image the images P1 ... P4 are superposed with appropriate shift to cause corresponding image point locations defining the selected layer to overlap and reinforce one another. The present invention reduces the effect of background image points from other layers by a process of selection or enhancement logic which is applied to each set of overlapping local image values relating to a corresponding image location in the selected section, to allocate to that location a related image value or a substantially zero value depending on whether the image detail is assessed as lying in the selected section or not. In one embodiment, Figure 4, the images P1 ... P4 are each scanned in 5 lines Z1 ... Z5 to form a corresponding video signal 9 which is applied to a parallel storage arrangement with different shift delays O,  DELTA  t1,  DELTA t2,  DELTA  t3. The overlapping signal values at each location Pn1 ... Pn4 are processed by an analyser 10a which causes a control stage 10b to transfer an image signal to an output register Sn for display only when a signal exceeds a threshold in all or most component images. Alternatively (Fig. 7 not shown) images P1 ... P4 can be multiplied together using a Titus tube, polarised light beam and associated television equipment. <IMAGE>

Title: Soft contact lenses
IPC: G02C7/04
Filed: 1979-10-05

Patent GB-2040163-A (GB)
Title: Facial-washing unit
IPC: A61H35/00
Filed: 1979-11-23
Abstract: The washing-unit has a washbowl 1 having in its base a cavity closed by a porous plate 5 which separates the washbowl 1 from an air chamber 7. Air is supplied to the chamber 7 from an electric blower 9 via an air supply tube 10. Air passing into wash water in the washbowl 1 through the porous plate 4 causes large numbers of small air bubbles in the wash water which assist in facial cleansing. The air supply tube 10 projects into the air chamber 7 so that any water leaking into the chamber 7 does not pass through the tube 10 to the blower 9. For the same reason the tube 10 is provided with at least one check valve 11a. Several embodiments of check valve are disclosed. The air supply is adjusted by a control device 15 which incorporates a thyristor to vary the electric power supplied to the blower 9. <IMAGE>

Title: Memory address translation system
IPC: G06F12/10
Filed: 1979-11-28
Abstract: In a named data processing system having a plurality, N, of memory modules, each module therein having a plurality of locations for storing data, a memory address translation apparatus translates a data job name and associated segmented address field into a memory module-page addressing pair wherein each and every storage location may be accessed by each and every job name. The job name and the associated segmented address field are each partitioned into most and least significant bit fields. Through translation a storage location is defined by the exclusive ORing, 23, of the least significant fields a2, b2, of the data job name and segmented address field. A memory module is defined by the modulo N sum, 27, of the output of XOR 23 and an address formed by the exclusive ORing, 21, of the most significant fields, a1, b2, of the job name and the segmented address field as permuted by an exclusive ORing, 25, with the least significant field, b2, of the segmented address field. Preferably, in order to increase address spacing activity, the most significant field, a1, of the job name is processed through a Fibonacci hashing process, 19, before any exclusive ORing process. <IMAGE>

Patent GB-2047505-A (GB)
Title: Decentralized call metering
IPC: H04M15/30
Filed: 1980-03-11
Abstract: In a telephone exchange system it is often required to be able to assess call charges at a decentralized location, such as at a calling subscriber's instrument, e.g. a coin box telephone. Such an arrangement includes a reference number memory (7) which holds codes for all charging zones accessible to a subscriber using that telephone instrument. When a wanted number is dialled, it is placed in a register (2) and its prefix code digits compared by a comparator (3) with the stored codes, which are read out cyclically by addressing means 4, 5. When the code for the wanted number is read out, as indicated by the comparator (3) the latter stops the read out, the point in the read-out cycle at which comparison is achieved is indicated by the setting of a counter (4). The setting of this counter causes the selection of a generator (one of Z1, Z2 ... Zn), which supplies meter pulses appropriate to the wanted line's zone and thus its charging rate, to an evaluator 11. <IMAGE>
